2.3 Commissioning
To commission the controller:
• Make certain that mounting and electrical installation are in compliance with the
relevant requirements
• Make all plant-specific settings as described in section "Parameter settings"
• Reset the attenuated outside temperature
• Make the functional checks
2.3.1 Functional checks
To facilitate commissioning and fault tracing, the controller allows output and input tests
to be made. With these tests, the controller’s inputs and outputs can be checked.
